CROSS REFERENCE TO RELATED APPLICATIONS

This application is a continuation of U.S. patent Ser. No. 14/461,166which is a continuation-in-part of U.S. patent Ser. No. 14/323,549 filedon Jul. 3, 2014; and U.S. patent Ser. No. 14/323,618 filed on Jul. 3,2014; and U.S. patent Ser. No. 14/461,128 filed on Aug. 15, 2014; allentitled “Secure Remote Actuation System” which are incorporated byreference herein for all that they contain.

BACKGROUND OF THE INVENTION

The present invention relates generally to remote actuation systemscomprising devices capable of performing remote operations. Examples oftypical remote actuation systems include thermostats, which may controlheating and cooling devices from a remote location, and garage dooropeners, which may provide remote access to secured areas. The remoteportions of such devices commonly require a portable power source, suchas a battery or photovoltaic cell. It is also typical of such devices tocomprise communications means, such as a radio frequency transceiver, toreceive and/or relay information.

For example, U.S. Pat. No. 8,331,544 to Kraus et al., which isincorporated herein for all that it discloses, describes a system thatremotely operates a door lock. The door lock may be powered by a batteryand be configured to send and receive radio frequency signals as part ofa mesh network. In such a mesh network, each connected device acts as acommunication node that can send and receive packets of information toany other device in the network. The door lock may further comprise amemory module where individual user codes are stored and a logic moduleto compare user codes to input codes at the door to allow accessdecisions to be made at the door without transmissions.

Such systems typically require continuing communications over a networkthat may cause rapid consumption of power. Thus, various attempts havebeen made to conserve power in such systems. For example, U.S. Pat. No.4,614,945 to Brunius, et al., which is incorporated herein for all thatit discloses, describes communicating information between a plurality ofinstrument monitoring units to a remotely located data collection unit.The monitoring units are radio frequency transponder circuits that areoperatively connected to one or more instruments whose parameters arebeing monitored. The transponders continuously monitor one or moreparameters of the instrument(s) with which they are associated. Thetransponders collect and accumulate parameter information and/or datafrom their associated instruments and continually listen for a “wake-up”signal from an interrogate receiver/data collection unit.

Despite these advances in the art, improved means of conserving power inremote actuation systems is desirable.

The network 110 may comprise a combination of computersystems interconnected by telecommunications equipment or cablesallowing information to be exchanged. In various embodiments, networkdevices may comprise a desktop or laptop computer, a cell phone, acomputer server, or other devices capable of communicating on such anetwork.

FIG. 2 shows an interior 206 of an embodiment of a network device 2200forming part of a network 210. The network device 2200 may comprise aplurality of components supported by a printed circuit board 209disposed therein. For instance, the embodiment of the network device2200 shown comprises a microcontroller 211 and an internal memory unit212 capable of obtaining and storing one or more user inputs from aremote input receptor (not shown). The network device 2200 may alsocomprise a communication device 213, such as a radio frequencytransceiver, for receiving the one or more user inputs. The radiofrequency transceiver may be a universal device capable of communicatingwith a plurality of other devices by reciprocating various radiofrequency transmissions.

FIGS. 3a and 3b show a perspective view and a partially-cutawayperspective view, respectively, of an embodiment of a remote inputreceptor 300 b comprising an interface 301 a and an interior 306 b witha plurality of components supported by a printed circuit board 309 bdisposed therein.

The printed circuit board 309 b may support at least a microcontroller311 b and a communication device 303 b. After a user supplies one ormore user inputs, the remote input receptor 300 b may transmit the oneor more user inputs to a network (not shown). The network may store andcompare one or more acceptable inputs to the one or more user inputs. Ifthe one or more user inputs correspond with the one or more acceptableinputs, the network may perform an operation.

The communication device 303 b may comprise a radio frequencytransceiver or other known communication apparatus. The communicationdevice 303 b may communicate at a sub-1 GHz frequency. It may beappreciated by those of ordinary skill in the art that communications atsub-1 GHz frequencies may be more capable of propagating throughenvironmental obstacles, such as a plurality of walls in a residentialhome, than communications at frequencies higher than 1 GHz. It maytherefore be desirable for said communication device 303 b to transmitsignals at a sub-1 GHz frequency. In some applications, it may bedesirable to communicate at a 2.4 GHz or 5.8 GHz frequency to achievecompatibility with other devices, such as those that communicate usingZigBee, Z-Wave, Bluetooth, or Wi-Fi.

The remote input receptor 300 b may be powered by a portable powersource 304 b, such as one or more galvanic or voltaic batteries, one ormore solar cells, or other known means of portable power. The remoteinput receptor 300 b may execute a low power function after a user hassubmitted a user input to the user interface 301 a. Such a low powerfunction may be executed for a predetermined amount of time or until auser starts to use the user interface 301 a again. When the low powerfunction is executed, the remote input receptor 300 b may cut power fromunneeded subsystems and reduce power in others until reactivated. Thislow power function, combined with not requiring continuous intermittentcommunication with the network, may enable the portable power source 304b of the remote input receptor 300 b to last significantly longer thanportable power sources of other known remote actuation systems.

The remote input receptor 300 b may further comprise one or moresurveillance devices 305 b, such as a security camera, a microphone, aproximity sensor, or other known surveillance means. For example, asecurity camera may be disposed within the interior 306 b of the remoteinput receptor 300 b, with a lens of the camera extending through anexterior 307 b of the remote input receptor 300 b. The one or moresecurity devices 305 b may continuously gather and transmit informationfrom an environment to a network (as shown in FIG. 1). Additionally, theone or more surveillance devices 305 b may trigger the remote inputreceptor 300 b to exit the low power function when the one or moresurveillance devices 305 b detect a user.

The remote input receptor 300 b may comprise one or more data connectionports 308 b for interacting with firmware of the remote input receptor300 b, such as altering or updating the firmware, running systemdiagnostics, or managing acceptable inputs and/or input parameters. Insome embodiments, such firmware functions may also be performed via anetwork (not shown). The one or more data connection ports 308 b may bedisposed on the interior 306 b of the remote input receptor 300 b to aidin preventing undesired access or accumulation of debris from thesurrounding environment. The one or more data connection ports 308 b maybe able to be accessed by detaching a portion of the exterior 307 b ofthe remote input receptor 300 b.
